An upper semicylindrical section 16 .of lthe head 13, is

Semi circular front and rear plates 23' 245; respectively; are provided on the section 16 and similar plates and 26 are provided on the section l5lf ln each of the front guide ways there is'disposed' a reciprocabl'e die carrier '27 provided ati ts inner end with segmental holding orje'inbracing di'e 28 suitably-secured thereto. These dies are each normally held out of operative "relatio,n" with the canfbo'dy by springs 29 one for each earner and; a1eadapted :to be forced inwardly into operative relation with respect to said body bycorresponding rollers 31 carried by an oscillatory ring'32.

In each of the guide ways at the rear of the head 13 there is provided a die carrier 33-.equipp'ed at its inner end with a flangdie 34- suitably secured thereto. The carriers 33 are normally urged inwardlyby springs 35 in which"position segmentary gIOOVeSfifi one inthe inner end of each die together form an' annular groove-to receive the end of the advancing can body. Each carrier '33 is provided near its. outer end with a roller 'or cam follower137 adapted to bee'ngagedby a cain surface 38in an oscillatory ring39 when the "latter is oscillated so that the dies 34l will"be drawn" ra- 'dially outwardlyto expand the endl'of the i can body into; a radially disposed flange.

The operation of'thediesQB a d earer se 'to, effect the flangin'goperation on the can body is substantially: the same as in my aforesaid cogpe'ndingapplication. The in- V 'fner" ends of the dies 28' and 34 converge toward said fends so-(that when-they are in innermost position-with'the dies 28' com- Ipletely embracing the can body and-the "dies'BQ forming a complete circular groove i adaptedto receive the end ofthe canbody the edges'of' the dies carriedby the'fupper section 16 and'the edges of the diescarried i i by the lower section 15 will extend to the line of division between the said sections.
